||Steam, coming from a turbine, enters the condensor at p=25 kPa with
a quality of x=0.95 at a rate of 8 kg/s. It is to leave the
condensor as saturated liquid at the same pressure. To that end
cooling water is available from a
nearby river but in order to not disturb the aquatic life in the river
the cooling water is not to experience a temperature rise of more than
12 °C. Specific heat of the river water : c = 4.19 kJ/(kg K)|
Contributions from kinetic and potential energies are to be neglected.
How much river water ( kg/s ) do we need at a minimum ? Please
state all your relevant equations.
